Backport patch from kernel 5.15 that mute error on EPROBE_DEFER with smempart parser. This parser require the smem device to be probed first and currently it may happen that mtd gets probed before the smem device causing an error on the smempart parser. This error may be confusing and should be muted. Signed-off-by: Christian Marangi <ansuelsmth@gmail.com>

Subject: [PATCH 13/14] mtd: parsers: qcom: Don't print error message on
|
|
-EPROBE_DEFER
|
|
|
|
Its possible for the main smem driver to not be loaded by the time we come
|
|
along to parse the smem partition description but, this is a perfectly
|
|
normal thing.
|
|
|
|
No need to print out an error message in this case.
